Question 1

what is genomic sequencing

Answer 1

the sequence of nucleotide bases can be determined for individual genes and entire genomes

Question 2

what is bioinformatics

Answer 2

computer science, statistics and biology

Question 3

what does bioinformatics allow

Answer 3

scientists to compare genomes from different species

Question 4

what does bioinformatics investigate

Answer 4

evolutionary pathways, inheritance and personalised medicine

Question 5

what other genomes have been sequenced

Answer 5

disease causing organisms, pests and species that are important models for research

Question 6

what does the comparison of genomes reveal

Answer 6

many genes are highly conserved across different organisms

Question 7

what is conservation

Answer 7

when the same or very similar sequences are found when comparing genomes

Question 8

what does genome conservation comparison determine

Answer 8

how closely or distantly an organism is related
higher conservation = more closely related

Question 9

what is phylogenetics

Answer 9

the study of evolutionary history and relationships
